Precision question 2 urgent!

You are measuring with a ruler the glass thickness of a microscope slide (~2 mm) and a table top (~1.5 cm). In which case will my measurement be more precise?

Is it

the table top? OR the microscopic slide OR the precision is the same as I am using the same instrument?
Um

Sorry, but full solutions are against the rules so I can't just say the answer (I will get reported and banned)

Note that 2mm is to the nearest mm, and 1.5 cm = 15mm is also to the nearest mm. What do you conclude about the precision of the measurements?

so the precision is the same then... am I right?

Yes! I agree. Both are measured to the nearest mm so precision is the same

What about the other question? You posted on my other post as well which was on the whiteboard. I chose that the precision is the same there as well. Is that correct? Thanks
